21 year old girl, looking for accommodation in Utrecht

Hello! I am Katherine, from Spain and I am about to finish my career in the following month. I am coming to Utrecht from September to February to do an internship in the University of Utrecht before starting my master and I am looking for a cheap and comfortable flat. I have already been sharing flat during the career and I have never had any problems, I consider myself a nice and fun flatmate :) 

I have heard that it may be difficult to find acommodation in Utrecht, so I am very open minded with the search! Please let me know if interested in sharing flat or if you have a room available!!
